Furthermore, in the present invention, the thermal pressing is made by thermal processes with a supersonic wave of power 1000 kw to 5000 kw. The cloth has a plurality of nodes which are spaced with a distance of 10 centimeter. The tenon has a bending portion by inserting the post into the via hole so that the handle is rotatable through 0 degrees to 360 degrees with respect to the plate. The handle is connected to the plate so that the duster is a two-stage device. The plate is a two stage device so that duster is a three-stage device. The non-weave cloth is a general used weave cloth. The curved plate is twisted through an angle between 90 degrees to 270 degrees.

The process of FIG. 2 will be described herein. The electric static non-weave cloth layers (812) and smooth non-weave cloth layers (812) are combined by a thermal process (803) to have net like non-weave cloth (804). Then by cutting to form a texture net non-weave cloth (806) of four layers. Then by combining (807) two layers of layers (806) and by a process (509) of adding meltable fiber yarns layers (808) to the cloth (806), a texture net non-weave cloth (811) of six layers is formed. Then the cloth (811) is added with electric static non-weave cloth layers (815). The layer (815) is formed with nets (816) to have not form non-weave cloth layers (817). Then the layers (817) are cut (818) to have strips (819) so as to get a 8 layer structure (820). Then The 8 layer structure is combined (830) with a handle and then is shaped (829) and then is cut (827) and thermally processed (828) so as to get a product (826) of the present invention.
